Abstrakt: 1.Ta in MoSe2 acts as an acceptor impurity, and alloying with it sharply increases the electrical conductivity of the compound.2.At x=0.12 · 10-2, the compound Mo1-xTaxSe2 is a nondegenerate semiconductor; compounds with x= 0.56 · 10-2 must be classed as semimetals.3.The effective masses of charge carriers in Mo1-xTaxSe2 alloys are close to m0. This indicates that holes generated as a result of alloying with tantalum are located in the valency zone (Fig. 1b).
